Conclusions and estimations:
-Crabby 1.0.0 (a Rust engine) is a great surprise (around 1350 Elo CCRL 4/40; no bugs and a nice play);
-PyChess 0.12.1 - the best chess engine (at the date) written in Python; a more elaborated evaluation than Sunfish 28_09_2014 (the same author);around 1170 Elo CCRL 4/40; together with its GUI is a superb Python chess project. Bravo again !
-Tiffanys 0.5 (Java) - plays nice , no bugs, around 1178 Elo CCRL 4/40. Supports only TC=X moves/Y minutes. Has its internal book (doesn't support GUI book).
-Talvmenni 0.1 (Java) is the single engine from this tournament tested by CCRL (1067 Elo CCRL 4/40).
